BACKGROUND: During a professional soccer season, training load (TL) will fluctuate due to the need to prepare for the next competition. Based on the technical staff’s daily and weekly evaluation, TL will be adjusted as they prepare the team and maximize individual performance and achieve a favorable result. Therefore, the programming of each match week (MW) TL may promote a favorable result. PURPOSE: The purpose of this study was to examine variation in daily GPS-derived TL variables based on match result using the Match Day Minus (MD-) system. This study provides descriptive TL data yet to be reported in this novel population. METHODS: Twenty-four male United Soccer League One (USL1) players were monitored through the full competitive in-season macrocycle. Using GPS units, metrics of interest were identified to best provide a full picture of training load. Duration (D), Total Distance (DT), High Metabolic Load Distance (HMLD), Total Loading (LT), Number of Accelerations (#A), and Number of Decelerations (#D), collectively make up weekly TL. The MD- system was used to categorize each training day. One-Way ANOVA was used for each MD- to compare results, with a Bonferroni Correction. RESULTS: D, DT, HMLD, and LT were the metrics of interest that had the largest effect throughout the MW. CONCLUSION: Based on the results of this study, weekly TL has been shown to influence match results in American professional soccer. Special consideration should be given to the metrics of interest during the MW in preparation for weekly competition.
